DiMastero, one of the new forum regulars has come up with a very novel way to use the new HiTechnic Magnetic Field Sensor; to relay messages by varying an NXT motor’s magnetic field. One position is set as a binary 0 and the opposite position is a 1. The user can set the angle of the reference motor to 0-255 degrees (8 bits). The angle is then sent to the sensor using a “communication” motor and read by the sensor. The NXT then copies the relayed angle to the other motor. It’s a pretty cool way to use this sensor!
